Weather in September
Temperature
The arrival of September signals a subtle shift in temperature, down from a fiery hot 95°F (35°C) in August to a tropical 88.9°F (31.6°C). In September, South Mansfield's temperature tends to fall to an average low of 67.6°F (19.8°C) during the night.Heat index
Throughout September, the heat index is computed to be an extremely hot 104°F (40°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. Take heed! Reflection from the snow can almost amplify the Sun's UV radiation by double.
